You should dress warmly and follow the advice of the health authorities as chilly weather conditions are expected to be at climax this month.
The Kenya Meteorological Department director Dr David Gikungu says the month of July marks the peak of the cold season, especially over the Highlands East of the Rift Valley and Nairobi county.
“The temperature forecast for July 2023 indicates that this zone, as well as parts of the Southeastern lowlands (parts of Kajiado), is expected to experience cool temperatures which are likely to be slightly warmer than the average for July. However, a few days may experience maximum temperatures below 180C and minimum temperatures below 100C,” Gikungu said in a forecast released on June 29.
Gikungu said most of the northern sector is likely to experience high temperatures except over Marsabit and parts of Isiolo counties where temperatures are expected to be moderate.
“The rest of the country is likely to experience moderate temperatures between 20 to 30 degrees Celsius. These temperatures are expected to be warmer than the July LTM (long-term mean).”
He said due to the expected cool and chilly conditions, cases of respiratory diseases such as asthma, pneumonia, flu, and the common cold are likely to increase in areas such as Nairobi, the Highlands East of the Rift Valley, parts of the Central and South Rift Valley, and parts of the Highlands West of the Rift Valley.
“To avoid contracting diseases, it is advisable to dress warmly and to follow the advice of the health huthorities. They are also advised not to use charcoal jikos in poorly ventilated houses because they emit carbon monoxide gas, which can kill if inhaled,” Gikungu said.
The director said several parts of the country will remain dry for the next three months.
